Can We Extract Lambda-Lambda Interaction from Two-Particle Momentum Correlation ?

We analyze the invariant mass spectrum of Lambda-Lambda in $^{12}C(K^-,K^+ Lambda Lambda)$ reaction at P(K^+)=1.65 GeV/c by using a combined framework of IntraNuclear Cascade (INC) model and the correlation function technique. The observed enhancement at low-invariant masses can be well reproduced with attractive Lambda-Lambda interactions with the scattering length either in the range a = -6 \sim -4 fm (no bound state) or a = 7 \sim 12 fm (with bound state). We also discuss Lambda-Lambda correlation functions in central relativistic heavy-ion collisions as a possible way to eliminate this discrete ambiguity.Comment: 4 Pages, LaTeX with psfig, embedded 4 ps figures.

Harmonic moments of the gluon density distribution in AA collisions

By using Monte-Carlo implementations of $k_T$-factorization formula with running-coupling BK unintegrated gluon distributions for nucleus-nucleus collisions, we compute higher order harmonic moments of the initial density distribution for both RHIC(Au+Au@200GeV) and LHC([email protected]) collisions. We study their sensitivity to the size of the valence parton distribution in the nucleon.Comment: 4 pages, 2 figures, references added, figure 2 is replaced by the results of central collision

An Analysis of the Financing of Higher Education in Georgia

This report addresses the issue of the financing of higher education in Georgia by comparing financing in Georgia with other states and examining how financing affects the student population in terms of performance, and retention rates. FRC Report 14

Mobilising Tax Revenue to Finance Development: The Case for Property Taxation in Francophone Africa

In the context of a widespread focus on decentralisation in Africa, there has been an imperative to find suitable ways to maximise potential own revenue sources at all sub-national government levels. This need in particular and the need for greater domestic resource mobilisation by African states in general have been exacerbated by the current global financial crisis that has led many countries into recession and left developed and developing countries alike scrambling to find solutions at home. Indeed, greater domestic resource mobilisation will go a long way toward providing African countries with the means to finance their development agenda without relying excessively on external assistance.

Subnational Value-Added Taxes: Options for Georgia

This report considers the implications of levying a "subnational value-added tax in Georgia as a replacement for the state corporate income and sales tax. FRC Report 16

On the Mordell--Weil group of the elliptic curve y^2=x^3+n

We study an infinite family of Mordell curves (i.e. the elliptic curves in the form y^2=x^3+n, n \in Z) over Q with three explicit integral points. We show that the points are independent in certain cases. We describe how to compute bounds of the canonical heights of the points. Using the result we show that any pair in the three points can always be a part of a basis of the free part of the Mordell--Weil group.Comment: 25 page
